Important :
Center lock disc lock cover, inner lock cover, only compatible with quick release hubs
clink to the below picture ??
The structural design advantages of the middle lock disc:
¨çIt can make the brake pads evenly stressed, which not only prolongs the
life of the pads, but also reduces the possibility of disc wear and deformation.
¨èUsing air and gaps to achieve the effect of heat dissipation.
